Answer:

$n =290$

$n =129$

The correct option is D

Step-by-step explanation:

From the question we are told that

The margin of error is $E = 0.23$

The largest value is k = 15

The smallest value is u = 7

From the question we are told the confidence level is 95% , hence the level of significance is

$\alpha = (100 - 95 ) \%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally population standard deviation estimate is mathematically represented as

$\sigma = \frac{Range }{4}$

Here the Range is mathematically represented as

$Range = k - u$

=> $Range = 15 - 7$

=> $Range = 8$

=> $\sigma = \frac{8 }{4}$

=> $\sigma = 2$

Generally the sample size is mathematically represented as

$n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2$

=> $n = [1.96 * 2 }{0.23} ] ^2$

=> $n =290$

Generally to obtain a conservatively small sample size the population standard deviation estimate becomes

=> $\sigma = \frac{Range }{6}$

=> $\sigma = \frac{8 }{6}$

=> $\sigma =1.333$

Generally the conservatively small sample size is mathematically evaluated as

$n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2$

=> $n = [1.96 * 1.333 }{0.23} ] ^2$

=> $n =129$

9+3.5g=11-0.5g brainliest to whoever gives steps

kow [346]

Answer:

The answer is g = 0.5

Step-by-step explanation:

1. Your equation is :

9+3.5g=11-0.5g

2. First, multiply both sides by ten

9 * 10 + 3.5 * 10 = 11 * 10 - 0.5 * 10

3. Next we refine the equation

90 + 35g = 110 - 5g

4. Now, lets subtract 90 from both sides

90 + 35g - 90 = 110 - 5g - 90

5. Simplify

35g + 5g = -5g + 20 + 5g

6. We then add 5g to both sides

35g + 5g = -5g + 20 + 5g

7. Simplify again

40g = 20

8. Now, divide both sides by 40

40g/40 = 20/40

9. And finally, simplify once again to get your final answer.

g = 1/2 or 0.5

I hope this helped :)

Which describes a non-uniform probability model? A) heads or tails from a coin flip B) the sum result of rolling two dice C) sel

irga5000 [103]

Answer:

Option B.

Step-by-step explanation:

The non-uniform probability is when the event is not same in the occurring of event.

Option A is uniform because there will be equal chance of getting head or tail.

Option B is non-uniform because sum can be any number if we get(3,4) it will be 7 and if we have (2,3) then it will be 5.

Option C is uniform because we have equal number of red and green balls so, selecting a ball from both will be same.

Option D is uniform because chance of 1,2,,3,4,5 or 6 will be equal chance from rolling a die that is 1/6 in all cases.

Therefore, Option B is correct
